dc.description.abstract | The West Coast resource is divided into the following “super” areas: Area 1-2: The most Northern region – only a very small tonnage is currently caught in this area. Area 3-4 (Areas 3 and 4 only) Area 5-6 (Areas 5 and 6 only) Area 7 (Dassen Island), and Area 8+ (areas to the south and east of Dassen Island, which include Area 8 (Cape Point), Area 10 (Hout Bay), Area 11 (False Bay), and Areas 12-14 (East of Hangklip). Figure 1 illustrates the West Coast rock lobster fishing zones and areas. Various methods have been used to collate data from Areas 3, 4, 5 and 6 to produce values for the “super” Area 3-6. Note that the convention used here for referring to split seasons is to quote only the first of the two years for each split season, i.e. the 1992/93 season is referred to here as “1992”. A size-structured modelling approach (as described in RLWS/DEC05/ASS/7/1/2) is used to model the dynamics of each super-areas independently. The area-disaggregated modelling approach assumes that recruitment from each area remains in that area and that there is no immigration or emigration between areas (of larvae or adults) | en_ZA |
